Well, A bill is born and being proposed the bill is referred to the committee, Which at this point the bill is examined carefully by the committee. Then, The bill is being marked up by the subcommittee

Committee action to report

the bill

Voting

And, If the bill passed the voting, it's referred to other chamber

Conference committee action, After the house and senate approve the bill, It can be brought up to the president. Hope That Helps!!~
